The Hutterites, one of America's fastest-growing Christian sects, have rigidly maintained their traditions, dress and language for over 400 years. Originally immigrants from Central Europe, they now live in 300 communities in the US and Canada, with families that marry and reproduce among themselves - closed groups of people who are religious cousins to the Amish. But recently they have been rocked by a wave of desertions. Tonight's film follows the crisis at the Flat Willow colony in Montana, where two-thirds of the Hutterite community have become born-again Christians. Families are divided and the future is bleak as a religious dispute looks set to destroy the Hutterite way of life forever.
